Jump starting
If the battery is flat then the car can be start-
ed with current from another battery.
The following points are recommended when
using a donor battery in order to avoid the
risk of an explosion:
1. Turn the car’s ignition to position 0, see
page 59.
2. Ensure that the donor battery is 12 volt.
3. If the donor battery is in another car,
switch off the donor car’s engine in the
other car and ensure that the cars do
not touch one another.
4. Connect the red jump lead to the posi-
tive terminal on the donor battery .
5. Open the clips on the front cover of the
battery in your car and remove the
cover, see page 187.
6. Connect the starter cable to the positive
terminal on the battery in your car,
located under a folding plastic cover.
7. Connect one clamp from the black jump
lead to the donor battery’s negative
terminal
.
8. Connect the other clamp to an earthing
point, (right-hand engine mounting at
the top, the outer screw head)
.
Check that the jump lead clamps are fixed
securely so that there are no sparks during
the starting procedure.
9. Start the engine of the "donor car". Let
the engine run a few minutes at a speed
slightly higher than idle (1500 rpm).
10.Start the engine of the car with the flat
battery. Do not touch the crocodile clips
during the start procedure. There is a
risk of sparks forming.
11.Remove the jump leads, first the black
and then the red. Make sure that none
of the clamps on the black jump lead
comes into contact with the battery’s
positive terminal or the clamp connect-
ed to the red jump lead.

IMPORTANT
Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.
WARNING
The battery can generate oxyhydrogen gas,
which is highly explosive. One spark, which
can be generated if you connect a jump
lead incorrectly, is sufficient to make the
battery explode. The battery contains sul-
phuric acid, which can cause serious burns.
If the acid comes into contact with eyes,
skin or clothing, flush with large quantities
of water. If acid splashes into the eyes, seek
medical attention immediately.
